Description: The two blocks are released from rest when r=0.8 m and θ=30^∘. Neglecting the mass of the pulley and the effect of friction in the pulley and between block A and the horizontal surface, determine (a) the initial tension in the cable, (b) the initial acceleration of block A,(c) the initial acceleration of block B.

step 1 Hello everyone here it is given two blocks are released from rest that is initial velocity is ze

Question

The two blocks are released from rest when $r=0.8 \mathrm{~m}$ and $\theta=30^{\circ}$. Neglecting the mass of the pulley and the effect of friction in the pulley and between block $A$ and the horizontal surface, determine (a) the initial tension in the cable, (b) the initial acceleration of block $A,(c)$ the initial acceleration of block $B$.
